Implanon?

I have had my implanon for a year now and every month I have had PMS followed by a light period but the last months I have had none of that! Is it normal to suddenly stop having periods or should I be worried?

I didn't have a period at all the entire time i had my implanon in (3 years first time, 2 year second) and it's a pretty common side affect, Although it could come back at anytime, So i'd enjoy the time it's gone while you can lol

My friend had it for 3 years and she would bleed for about 3 months straight, then she wouldn't bleed at all for 3 months. It was like that the whole time she had it.

I know that just not having it or having prolonged bleeding can be a side effect. I was just worried because I have had a regular period for 10 months on it and then it just stopped out of no where!
